  2. 1. Impact of dependencies in risk assessments of power distribution systems

    Author : Karin Alvehag; Lennart Söder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Abstract :  Society has become increasingly dependent on electricity, so power system reliability is of crucial importance. However, while underinvestment leads to an unacceptable number of power outages, overinvestment will result in costs that are too high for society. The challenge is to find a socioeconomically adequate level of risk. READ MORE

The extension makes it possible to sort out responses on the participation and hour margins. READ MORE

  6. 4. Optimal Stopping and Model Robustness in Mathematical Finance

    Author : Henrik Wanntorp; Johan Tysk; Svante Janson; Boualem Djehiche; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimal stopping; model robustness; American options; free boundary problems; hedging; option pricing; Mathematical statistics; Matematisk statistik;

    Abstract : Optimal stopping and mathematical finance are intimately connected since the value of an American option is given as the solution to an optimal stopping problem. Such a problem can be viewed as a game in which we are trying to maximize an expected reward. READ MORE

  7. 5. Two Essays in Empirical Finance: Unit-Root Testing in the Presence of Structural Breaks

    Author : Florin G. Maican; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Essay 1: Real Exchange Rate Adjustment in European Transition Countries Essay 1 presents unit-root test results for real exchange rates in ten Central and Eastern European transition countries relative to the Euro during 1993:01-2005:12. Because of the shift from controlled to market economies and the accompanying crises, failed policy regimes and changes in exchange rate regimes, appropriate tests in transition countries require allowing for both structural changes and outliers.
